8. In Flash Professional 8 only, in the Accessibility panel s Tab Index field, you may enter the number corresponding to the object s tab index value, if appropriate. The tab index determines how users can use the Tab key to navigate through and select one of the buttons, check boxes, and other controls in your movie. For example, suppose that you have three buttons with a tab index of 1, 2, and 3, respectively. When the movie starts, if the user presses the Tab key three times, the button with the tab index of 3 would be selected for input. If you have the Accessibility panel open when nothing in your movie is selected, the panel offers you the option to Make Movie Accessible, which is selected by default. This allows screen readers to read the different objects in the Flash movie. You definitely want this option selected if you want to make your movie accessible to screen readers and other hardware and software for people with disabilities. Of course, you also have to name each object by using the Accessibility panel, as we describe in the preceding steps, for this to be useful. Sharing Libraries on the Run A runtime shared library is a library in a movie that has been posted to a Web site and is used by another Flash Player file (.swf). The movie using the shared library object doesn t contain the object but just uses it from the shared library. Shared libraries can help make it easier to manage and revise the elements in your movies. For example, you can use a single shared library for multiple Flash movies to access a sound; when you update the sound in the shared library, the sound is updated for all the movies that share it. Creating a shared library A runtime shared library can be a movie clip, a button, a graphic symbol, a sound, a bitmap, or a font symbol. (See Chapter 7 for the lowdown on symbols.) You create a runtime shared library when you want to make an element in your movie available to other SWF player files. You do this by defining linked objects in a movie s library. To create a runtime shared library, follow these steps: Chapter 12: Putting It All Together 281
